Materials and methods: A descriptive, prospective, and cross-sectional study was performed from January 2011 to April 2018.  Results: Hundred and sixty-four patients in whom the implant was not palpable were reviewed, the time between insertion and removal averaged 3.3 years (maximum 10 years and minimum 3 months). Three implants were inserted in the right arm, the rest on the left one. Forty-seven implants were found in fatty tissue (29%), 18 in fascia (11%), 94 in muscle (57%), 2 in the armpit (1.2%), and 3 were not found (1.8%).  Conclusions: The no palpable implant is caused by an incorrect insertion technique. Migration should not be assumed as a cause of difficult location. Amount of non-palpable implants is not possible to determine due to a lack of records, but approximately 3% are considered non-palpable. Ultrasound has proven to be the study of choice to locate an incorrect inserted implant. In this case, the total number of implants was located, except in two patients.]]></p></abstract>

Materials y métodos: Estudio clínico descriptivo, prospectivo y transversal, realizado desde enero de 2011 hasta abril de 2018 en el servicio de planificación familiar del Hospital General de México Dr. Eduardo Liceaga.  Resultados: Se incluyeron 164 pacientes con implantes no palpables, de los cuales 161 se localizaron por ultrasonido. El promedio entre la inserción y el retiro fue de 3.3 años. Tres implantes fueron insertados en el brazo derecho y el resto en el izquierdo; tres no se encontraron.  Conclusión: Por su fácil acceso y simplicidad, el ultrasonido es el método de elección para localizar implantes profundos no palpables.]]></p></abstract>
